A seamount is a large submarine landform that rises from the ocean floor without reaching the water surface (), and thus is not an island, islet, or cliff-rock.Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height.
In the ocean basins, ocean island basalts form seamounts, [3] and in some cases, enough material is erupted that the rock protrudes from the ocean and forms an island, like at Hawaii, Samoa, and Iceland. Over time, however, thermal subsidence and mass loss via subaerial erosion causes islands to become completely submarine seamounts or guyots.
The Hawaiian–Emperor seamount chain is a mostly undersea mountain range in the Pacific Ocean that reaches above sea level in Hawaii.It is composed of the Hawaiian ridge, consisting of the islands of the Hawaiian chain northwest to Kure Atoll, and the Emperor Seamounts: together they form a vast underwater mountain region of islands and intervening seamounts, atolls, shallows, banks and reefs ...
(Ma = million years) Map of the Hawaiian Islands and some of the Emperor seamounts showing progression in selected erupted lava ages along the chain (Ma = million years) The Hawaiian–Emperor seamount chain is a series of volcanoes and seamounts extending about 6,200 km (3,900 mi) across the Pacific Ocean.

For instance, water causes magma to cool and solidify much more quickly than in a terrestrial eruption, often turning it into volcanic glass. The shapes and textures of lava formed by submarine volcanoes are different from lava erupted on land. Upon contact with water, a solid crust forms around the lava.
